Why does my Sapphire RX 7650 GRE 8G experience massive FPS drops in complex scenes in Dragon Age: The Veilguard?

Every time I stepped into a major city, my frame rate would dive from 60 FPS to a pathetic 25 FPS, making the controls feel like I was playing in molasses. With the Sapphire RX 7650 GRE's 8GB limit, maxing out textures pushed usage to 7.9GB, triggering an incredibly slow system memory swap. I tried cranking my Windows virtual memory up to 64GB, but that just hammered my CPU I/O and actually made the stutters worse—absolutely infuriating. I eventually dialed the texture quality down from Ultra to High and enabled memory compression in the Adrenalin software. In side-by-side tests, my 1% lows jumped from 22 FPS to 48 FPS, and scene transitions became night-and-day smoother. I did notice some distant textures looking a bit blurry, but a quick sharpen filter fixed the visual balance. VRAM usage now sits comfortably at 6.2-6.8GB with core temps at 68-75℃. Performance logs show the overflow is gone, and the input lag is finally nonexistent.
